Graphic communication processing apparatus capable of chaining graphic information with a small number of processes

A graphic information processing apparatus comprising:

• an input device for inputting graphic information, including coordinate values for a plurality of coordinate points of graphic data, and process command data for said graphic information;
• a memory having first and second memory areas for storing graphic information received from said input devices;
• a display device for displaying said graphic information stored in said memory;
• and
• a processor connected to receive said process command data from said input device, and including graphic information store means for storing said graphic information from said input device in said memory, stored information change means for changing graphic information stored in said memory;
• display means for reading graphic information stored in said memory and for supplying said read graphic information to said display device and means responsive to said process command data from said input device for operating one of said graphic information store means, said store information change means and said display means;
• wherein said graphic information store means comprises:
• coordinate value store means for storing coordinate values of each coordinate point of said graphic information from said input device in said second memory area;
• and
• coordinate point store means for storing in said first memory area data representing each coordinate point and pointers indicating store areas of said coordinate values stored in said second memory area.
